Jill wants to buy a new coat that costs $35. She can save $3 per week from her paper route.
How long will it take Jill to save enough money for the coat?
O A. 3 weeks
B. 12 weeks
OC. 20 weeks
O D. 1 year
O E. 10 weeks

B. 12 weeks

Step-by-step explanation:

12 weeks because by then she will have earned $36 which is more than enough to buy the coat.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
